Lionel is a great entertainer - likeable, funny, involved with the audience - who kept us going the entire evening. We laughed, we danced, we finished his sentences, we sang. Did I say we danced? He was dynamic and backed up by very talent musicians who were also entertaining (especially his saxophone/harmonica player).
Here is a picture of his arrival on stage, "Hello," he said. "Is it me you're looking for?"
Oh, and let me not forget that Ce Lo Green opened the show and warmed up the audience for almost 50 minutes before Lionel came out.
